IMPROVEMENT IN MACHINES' FOR C'OPING SASH.

Specification forming part of Letters Patent No. 41,706, dated February23, 1864.

Vmode of coping or scribing window-sash bars at their intersection orangles and I do hereby declare that the following is a clear and exactdescription thereof, reference being had to the annexed drawings, and tothe letters of reference marked thereon.

The nature of my invention consists in the form of a gouge or cutterworked by means of a slide and lever, which hasthe cuttingedge or pointso formed as to strike the bar in an oblique or angular direction to thecenter of the gouge or cutter, as shown by F F,

. Fig. 2, thereby obviating the diiiiculty ot' splinterin g the bar whencuttin g directly through and across the ber of the wood at one cut,which would be the natural conse quence of a cut made directly throughthe bar by a common gouge as used by hand, the bar in that case havingto be turned over and cut from both sides, which is still liable tosplinter from a slip of the hand or gouge.

In order that others may construct or use my improvement, I will'further describe it as follows Figure l is the plan. Fig. 2 is thelongitudinal elevation. Fig. 3 is a transverse section. Fig. 4 is thefront or operating side. Fig. 5 is the perspective.

A A, Fig. 2, is the bed-plate, on which to construct the slide andlever.

B B B, Fig. 2, is the stand through which Y the slide works.

C C, Fig. 2, is the lever.

D D, Fig. 2, is the slide.

E, Fig. 2, is a movable collar, by which the gouge is adj usted to themounting on the bars.

F F, Fig. 2, thergouge or cutter.

G, Fig. 2, is a stop for the bar to prevent the gouge cutting too deep.

H, Fig. 2, is a back or rest, with a loose L piece, I, attached by meansof two small setscrews, as shown in perspective, Fig. 5, to support thebars while being cut, or in other words to resist the pressure of thegouge or cutter.

K, Fig. 2, is a flange, by which to hold the machine in a vise orotherwise while being operated.

L, Fig. 2, shows the section of a sash-bar in position to be cut, whichis done by moving the lever from left to right, or, in other words,directly forward toward the bar, when it will produce the direct cut.

What I claim as new, and desire to secure by Letters Patent, is-

The combination of gouge F, slide I), and lever C, when constructed andoperating substantially as described. 1
